PNEUD'IATIG WATER LIFT.

Application filed July 27,

To all whom it may concern: 7

Be it known that I, LOUIS E. Morrison, a citizen of the United States, residing at Salida, in the county of Chafi'ee and State of Colorado, have invented certain new and useful Improvements in Pneumatic Water Lifts, ofwhich the following is a specification.- 7

This invention relates to pneumatic water lifts and the object thereof is to so construct such an apparatus that when a faucet is opened water fresh from the well will be discharged therefrom, without having first. bee-n pumped into a container. Another objectis to provide air controlled piston operated means for raising the water from the well. I With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the vention herein disclosed may be made within th'escope of what isclaimed without departing from the spirit of the inventlon.

In the accompanying drawings: Figure 1 represents a side elevationfpartly in section of the apparatus constituting this invention; and

Fig. 2 is a detail sectional view of a portion of the valve casing and valve which controls the air sup-plied to the cylinder.

v 5 In the embodiment illustrated a water .tube or pump casing .1 is shown which is designed to be lowered into the well, a portion only of such casing being illustrated. This casing or tube 1 is connected by a T coupling 2 with a discharge pipe 3 which is here shown extended laterally at right angles from tube 1 and is connected-by a T coupling 4 with a pipe 5 which discharges into a closed container 6. A faucet for withdrawing water from the pipe 3 is located at a point remote and is not shown, as it 1s of ordinary construction and illustration thereof is not deemed necessary.

A pipe 7 leads from thecontainer 6 and is here shown L-shaped with the long arm 7 7 thereof in upright position and having located at its upper end a valve casing 8 in which is mounted to move vertically ag fluidactuated disk-valve 9 carried by an upward- 1y projecting stem 10. This valve 9 is designed when in lowered position to rest on 1920. Serial No. 399,362.

the upper end of the pipe 7 sothat when water raises in said pipe it will lift this disk-valve 9, for a purpose presently to be described. The stem 10 has an aperture'o-r bore 11 extending transversely therethrough which is designed to register with an air supply pipe 12 leading froma tank T when the valve 9 is inlowered position, as shown in Fig. 1. V v A coiled spring 18 is mounted in an upstanding tube 13 between the upper end of the stem 10 and the lower end of anadjusting screw 14: and operates to normallyhold the valve 9 in lowered position, shownin Fig. 1. The screw let is designed for controlling the tension of spring 13 so that, the power required to elevate disk 9 may be varied. I

A cylinder 15. is mounted on the platform P which also supports the containerfi and the tank T and has mounted to reciprocate therein a piston 16' carried by a rod 17 "This rod 17 extends through the top ofthecyli n der 15 and through a valve casing 19 mounted on said cylinder and the other end of the rod projects downwardly through' the bottom of the cylinder, the platform P,'-'a'nd into the pump casing 1 and has connected with it the ordinary means for lifting water in the tube when the piston16'is reciprocated.

The upper end of the pump rod 17 outside the casing 19 is provided with a head 18 which projectsinto position to overhang a valve trip rod 25 operable in a mannerpresently to be described.

The top of the cylinder has an opening 20 which communicates with the valve casing 19 to permit the entrance of air from said casing into the top of the cylinder, while a pipe 21 connects said casing with the bottom of the cylinder discharging into the cylinderbelow the piston 16. i

A. slide valve 22 is mounted in the, valve casing 19 and has a stud 23 projecting from one end thereof which is engaged with a longitudinally slotted obliquely disposed arm 24 carried by the trip rod 25 so that when said rod is raised the valve 22 will be moved toward the right to uncover the top of pipe 21'and afford communication between the interior of the casing 11/ and the lower portion of the cylinder 15 to permit air entering the casing 19 through pipe 12 to pass downwardly through pipe 21 into the cylinder 15 for raising the piston 16 When,

this piston 16 rises suiiiciently to engage the lower end of the trip rod 25 said rod will be elevated and thereby operate to shift the valve 22 in the manner just described. The lowering of the piston will cause the head 18 on the rod 17 to engage the upper end of the rod 25 and thereby close the valve 22 by shifting it toward the left.

In the use of this apparatus when the faucet through which the water is to be drawn is closed sufiicient water is left in the system to fill the COI-Yt-alDGL" 6 and to rise up through pipes 7 and 7 against the diskvalve 9 and elevate said valve so as to raise the stem 10 sufficiently to cut off communication between the tank T and the air delivery pipe 12, thereby rendering the pump inoperative. Immediately the faucet isopened the water in the container 6 will be drawn out thereby lowering the pressurein pipe 7* which will lower under the action of its spring 13, thereby bringing the opening 11 in the stem 10 into register with pipe 12, as is shown in Fig. 1. WVhen the valve assumes this position the compressed air in tank T will flow through the pipe 12 into the valve casing 19 and flowing through pipe 21will. enter the cylinder 15 under the piston 16 thereby causing said piston to rise in the cylinder and operate in the manner above described, reciprocating back and forth and thereby elevate water through the tube 1 and discharge it tlirough p'ipe 3. This operation will continue: as long as the faucet remains open. Immediately the faucet is closed the water will rise into the container 6 and pipes 7 and '7 elevating valves 9 and cutting off communication between the tank T and pipe 12, thereby cuttin off the operation of the pump.

Fromtheabove description it will be obvious that with an apparatus constructed as above described and shown in the drawings, whenever the faucet is: opened after contents in the container 6 have flowed out thereinvention together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent, is:

In an apparatus of the class described a cylinder, a piston operable in said cylinder, a rod extending through the cylinder to which said piston is fixed, a compressed air supply, means for cbnnec'ting said supply with said cylinder, a valve for controlling the air supply to the cylinder, a triprod equipped with an obliquely and upwardly disposed longitudinally slotted arm, a stud carried by said valve and extending through the slot in said arm, said trip rod being arranged in the path of the piston and movable in one direction by the upward movement of the piston, and means carried by the piston for engaging said rod to move it in the opposite direction on the lowering of the piston.

In testimony whereof I afliX my signature in presence of two witnesses.
